Viadd Chemical Company is one reliable L-Leucine exporter from China!

 Leucine is an amino acid which was discovered in its impure form in cheese back in 1819, and just a year later - in its crystalline form from muscles and wool. This amino acid got its name from the Greek word leukos, which means "white", since at that time the purification of the substance in question from natural to a white, crystalline state was considered to be noteworthy. Only in the end of the 19th century the structure of Leucine was established by laboratory synthesis. This amino acid is also recognized as one of the three branched-chain amino acids.

 As an essential amino acid, leucine is not synthesized in animals, hence it must be ingested, usually as a component of proteins. It is synthesized in plants and microorganisms via several steps starting from.

 Unlike other amino acids, essential amino acids can’t be produced by the body, so we have to get them from food or supplements. Leucine and two other essential amino acids, isoleucine and valine, are needed to build protein. Because of their structure, they are called branched-chain amino acids, or BCAAs. Leucine is the fourth most abundant of all amino acids in muscle, and together the BCAAs makes up about a third of muscle protein.

 As a dietary supplement, leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins.Leucine is utilized in the liver, adipose tissue, and muscle tissue. In adipose and muscle tissue, leucine is used in the formation of , and the combined usage of leucine in these two tissues is seven times greater than its use in the liver.Leucine is used in the liver, adipose tissue, and muscle tissue. Adipose and muscle tissue use leucine in the formation of sterols.

【Main Functions】

1. Maintaining blood sugar levels effectively

2. Increases growth hormone production.

3. L-Leucine combines with isoleucine and valine to protect and provide fuel to the muscles, and also helps to increase your endurance level and boost energy.

4. Preserve lean muscle mass so that it doesn't break down as quickly during the aging process.

5. Speed the recovery process for muscle damage and skin injuries.

1. Building Protein

Unlike other amino acids, essential amino acids can’t be produced by the body, so we have to get them from food or supplements. Leucine and two other essential amino acids, isoleucine and valine, are needed to build protein. Because of their structure, they are called branched-chain amino acids, or BCAAs. Leucine is the fourth most abundant of all amino acids in muscle, and together the BCAAs makes up about a third of muscle protein. BCAAs fuel muscle metabolism and protect muscle from stress by stimulating protein synthesis, increasing reuse of amino acids, and decreasing protein breakdown under stress.

2. Regulating Blood Sugar

The body uses glucose, or sugar, for energy. Many amino acids produce glucose, but leucine is the only one that can substitute for glucose during fasting. Increased glucose prevents the body from using muscle for energy during intense workouts.  Viadd chemical supply high quality L-Leucine. Leucine is more effective at regulating blood sugar levels than isoleucine and valine, because they are converted to glucose more slowly.

3. Building Muscle

Leucine is also thought to stimulate insulin release. Insulin, an anabolic hormone, is needed to enable key nutrients, such as glucose, amino acids and creatine, to enter muscle cells. Insulin stimulates protein synthesis and inhibits protein breakdown. BCAAs are the primary fuel in anabolic reactions, so they provide a reasonable and safer alternative to steroids for body-builders, weight lifters, and other athletes. During training, they enhance muscle-protein metabolism, decrease exercise-induced protein degradation, and support oxidative metabolism in muscles during strenuous exercise.

4. Medical Uses

Stress states decrease BCAA levels. Surgery, trauma, cirrhosis, infection, fever, starvation and malnutrition stress the body, making protein break down faster than normal. BCAA supplements can prevent or reverse this effect. Intravenous solutions containing BCAAs are given to people recovering from trauma and surgery to help bones, skin, and muscle heal. In diseases that affect the muscles, BCAAs are used to decrease wasting. According to Medical News Today, recent reports also suggest that leucine supplements can prevent the muscle loss that comes with aging. Astronauts use them to help withstand the effects of space travel on the body.

5. Brain Functions

BCAAs are constituents of neuropeptides—biochemical messengers from the brain to the body’s cells—and neurotransmitters, like endorphins and enkephalins, which produce calming and pain-relieving effects. One form of leucine prevents these natural painkillers, produced by the body, from breaking down. Enkephalins may lower levels of serotonin and dopamine in the brain; however, and According to “The Healing Nutrients Within,” at least one study found very high levels of leucine in people with depression. BCAA supplements can help treat and even reverse hepatic encephalopathy, a brain condition related to alcoholism and severe liver or spleen disease.

6. Leucine is one of nine essential amino acids in humans (provided by food), Leucine is important for protein synthesis and many metabolic functions. Viadd chemical supply high quality L-Leucine. Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. Leucine is available in many foods and deficiency is rare.

7. Weight Loss Benefits

Another animal study, this one appearing in the May 2009 issue of "Medicine & Science in Sports & Exercise," evaluated the effect of L-leucine along with exercise on weight loss in rats who previously ate a high-fat diet for 15 weeks. Researchers divided these rats into two exercise groups, with one group receiving leucine supplementation. Exercise combined with leucine had stronger effects on weight loss than exercise alone.
 

【Applications】

1. L-Leucine is the forth most concentrated amino acid in skeletal muscle tissue - it comprises about eight percent of the total amino acid count in your body's protein structures. As one of the three BCAA's, L-Leucine is essential to your basic health.

2. L-Leucine has both athletic and medical applications.

3. L-Leucine maintains nitrogen balance, and it has also been shown to enhance declined thinking abilities as physical activity becomes more intense. L-Leucine also works to heal bone, skin and muscle tissue.

4. As a food additive, L-leucine has E number E641 and is classified as a flavor enhancer.
 

 How much you need?

The ideal amount of leucine to take is a matter of debate. When single doses have been studied, intake of as little as 2.5 grams of leucine stimulated protein synthesis. In long-term studies, leucine intakes equivalent to 8 or more grams per day are recommended in divided doses so that at least 2.5 grams of leucine are consumed at each meal. Viadd chemical supply high quality L-Leucine.

The best food sources of leucine include any proteins from animals that naturally contain all the essential amino acids. The protein source with the highest leucine content is whey, which contains about 10% leucine or 10 grams per 100 grams of protein. If you drink a whey protein shake that has about 25 grams of protein, you would get about 2.5 grams of naturally occurring leucine. Other protein supplements like casein and soy contain less leucine, about 8%.
